| 摘 要： | 旨在为苹果幼园生产大豆提供依据。以‘秦豆12’为材料,果树行间套种5行（处理1）、4行（处理2）和3行（处理3）并以不套种为对照,探究不同处理条件下的大豆产量、农田土壤特性、杂草数量和农田小气候。结果表明：1龄、2龄和3龄果园中处理1、处理2和处理3产量分别最高,且随着树龄的增加,同一处理产量边际效应降低;与不套种大豆相比,套种大豆可使土壤容重降低8.33%,土壤含水量增加13.08%,土壤有机质、速效N和速效K分别提高16.67%、20.33%和9.35%,杂草减少58.10%和相对湿度增加4.47%,并可实现160.90%的利润率。苹果幼园套种大豆具有明显的经济效益和生态效应,1龄果园行间套种5行、2龄果园行间套种4行和3龄果园行间套种3行具有明显的产量和效益优势。

| Abstract: | The aim is to provide a theoretical basis for soybean production in the young apple orchards. ‘Qindou 12’ was used as material, and three treatments were set up, including intercropping 5 rows soybean (treatment 1), intercropping 4 rows soybean (treatment 2), intercropping 3 rows (treatment 3) and no intercropping as the control (CK). The soybean yield, soil traits, weed amount, and agricultural microclimate were studied in different treatment conditions. Results showed that treatment 1, treatment 2, treatment 3 had the highest yield in 1-year, 2-year, 3-year orchard, respectively. The yield marginal effect of the same treatment decreased as apple tree-age increased. Compared with CK, intercropping soybean in apple orchard decreased soil volume weight by 8.33%, increased soil moisture content by 13.08%, improved soil organic matter, available N, and available K by 16.67%, 20.33%, and 9.35%, respectively, reduced weed amount by 58.10%, increased the relative humidity by 4.47%, and obtained 160.90% of profit rate. Intercropping soybean in young apple orchard had obvious economic benefit and ecological efficiency, and significant advantages of yield and benefit were found when intercropping 5 rows soybean in 1-year orchard, intercropping 4 rows soybean in 2-year orchard, and intercropping 3 rows soybean in 3-year orchard. |
